Book Description
Pollinators-insects, birds, bats, and other animals that carry pollen from the male to the female parts of flowers for plant reproduction-are an essential part of natural and agricultural ecosystems throughout North America. For example, most fruit, vegetable, and seed crops and some crops that provide fiber, drugs, and fuel depend on animals for pollination. This report provides evidence for the decline of some pollinator species in North America, including America's most important managed pollinator, the honey bee, as well as some butterflies, bats, and hummingbirds. For most managed and wild pollinator species, however, population trends have not been assessed because populations have not been monitored over time. In addition, for wild species with demonstrated declines, it is often difficult to determine the causes or consequences of their decline. This report outlines priorities for research and monitoring that are needed to improve information on the status of pollinators and establishes a framework for conservation and restoration of pollinator species and communities.

Book Description
A comprehensive review of the honeybees of Africa on a subspecies as well as by country basis. Includes an updated multivariate analysis of the subspecies based on the merger of the Ruttner database (Oberursel) and that of Hepburn & Radloff (Grahamstown) for nearly 20,000 bees. Special emphasis is placed on natural zones of hybridisation and introgression of different populations; seasonal cycles of development in different ecological-climatological zones of the continent; swarming, migration and absconding; and an analysis of the bee flora of the continent. The text is supplemented by tables containing quantitative data on all aspects of honeybee biology, and by continental and regional maps.

Book Description
There is consensus that loss of biodiversity is a defining feature of the Anthropocene, with potentially severe consequences for human food security and well-being. Of particular concern are global declines in insect pollinators, such as bees, flies, beetles and butterflies, as their roles in sustaining ecosystem functions and ensuring food production are indispensable. A wide array of abiotic and biotic stressors likely govern the observed insect declines and losses of wild and managed insect pollinators, respectively. For instance, habitat destruction and fragmentation can not only lead to smaller and isolated populations that are vulnerable to environmental stochasticity or inbreeding depression, but also lead to poor nutrition as floral abundance and diversity are reduced. Further key stressors are pests and pathogens, climate change, intensified agriculture and environmental pollution (e.g., pesticides). These environmental stressors may interact with one another and generate complex effects that amplify the direct consequences of a single given stressor. Unfortunately, there is a lack of knowledge concerning how even the most important environmental stressors may interact to affect insect pollinators. The goal of this effort is to develop a platform that brings together the latest information on how abiotic and biotic stressors interact to impact insect pollinator health. Only by bringing together different lines of evidence will we be able to better predict how these environmental stressors will affect insect pollinators. An improved understanding will also facilitate the development of more effective and sustainable management strategies that will enable stakeholders to implement adequate and sustainable measures to safeguard insect pollinators. This Research Topic welcomes both Original Research and Reviews, as well as Commentary or Opinion articles that address the topic of environmental stressor interactions, and their impact on insect pollinator health. Submissions should be based on, but not limited to: - How combined environmental stressors affect insect pollinators using molecular, physiological, behavioral, ecological or evolutionary approaches - Experimental or survey work conducted under laboratory, semi-field, or field conditions - Unravelling the mechanisms underlying combined stressor interactions - What can be done to limit the impact of combined environmental exposure in the field

Book Description
Bees provide a critical link in the maintenance of ecosystems, pollination. They play a major role in maintaining biodiversity, ensuring the survival of many plants, enhancing forest regeneration, providing sustainability and adaptation to climate change and improving the quality and quantity of agricultural production systems. In fact, close to 75 percent of the world’s crops that produce fruits and seeds for human consumption depend, at least in part, on pollinators for sustained production, yield and quality. Beekeeping, also called apiculture, refers to all activities concerned with the practical management of social bee species. These guidelines aim to provide useful information and suggestions for a sustainable management of bees around the world, which can then be applied to project development and implementation.

Book Description
Honeybees are as small as flies or as large as hornets, nesting in nar row cavities of trees and rocks or in the open on large limbs of trees 30 m above ground. They occur in tropical zones and in the forests of the Ural mountains, they survive seven months of winter and even longer periods of drought and heat. Historically, they lived through a extended time of stagnation in the tropics from the mid-Tertiary, but then experienced an explosive evolution during the Pleistocene, re sulting in the conquest of huge new territories and the origin of two dozen subspecies in Apis mellifera. This vast geographic and ecologic diversification of the genus Apis was accompanied by a rich morphological variation, less on the level of species than at the lowest rank, the subspecies level. Variation being exclusively of a quantitative kind at this first step of speciation, tradi tional descriptive methods of systematics proved to be unsatisfactory, and honeybee taxonomy finally ended up in a confusing multitude of inadequately described units. Effective methods of morphometric-sta tistical analysis of honeybee popUlations, centered on limited areas, have been developed during the last decades. Only the numerical characterization of the populations, together with the description of behavior, shows the true geographic variability and will end current generalizations and convenient stereotypes.

Book Description
A unique and personal insight into the ecology and evolution of pollinators, their relationships with flowers, and their conservation in a rapidly changing world. The pollination of flowers by insects, birds and other animals is a fundamentally important ecological function that supports both the natural world and human society. Without pollinators to facilitate the sexual reproduction of plants, the world would be a biologically poorer place in which to live, there would be an impact on food security, and human health would suffer. Written by one of the world’s leading pollination ecologists, this book provides an introduction to what pollinators are, how their interactions with flowers have evolved, and the fundamental ecology of these relationships. It explores the pollination of wild and agricultural plants in a variety of habitats and contexts, including urban, rural and agricultural environments. The author also provides practical advice on how individuals and organisations can study, and support, pollinators. As well as covering the natural history of pollinators and flowers, the author discusses their cultural importance, and the ways in which pollinator conservation has been portrayed from a political perspective. The book draws on field work experiences in South America, Africa, Australia, the Canary Islands and the UK. For over 30 years the author has spent his career researching how plants and pollinators evolve relationships, how these interactions function ecologically, their importance for society, and how we can conserve them in a rapidly changing world. This book offers a unique and personal insight into the science of pollinators and pollination, aimed at anyone who is interested in understanding these fascinating and crucial ecological interactions.

Book Description
This is a practical tool to help beekeepers, veterinarians and beekeeping advisory services to properly identify main honeybee diseases and to take the most appropriate actions in the apiary to control and/or prevent disease outbreaks. This publication follows the TECA publication Main bee diseases: good beekeeping practices (2018) which provided a more general overview of good beekeeping practices for bee diseases. This manual is a unique publication because, through its presentation of practical information, simple visuals, and understandable content, it helps beekeepers to correctly identify main honeybee diseases in a timely manner. More specifically, the manual creatively illustrates actions which facilitate the identification of disease symptoms. It also presents a comprehensive list of good beekeeping practices to adopt in the apiary as well as biosafety measures to reduce the risk of the introduction and the spread of main honeybee diseases. The manual’s overall objective is ultimately to support a more sustainable beekeeping sector.
